The second casing 102 has two second recesses 1020 which are respectively located on two opposite sides of the second casing 102. When the first casing 101 is assembled with the second casing 102, the first recess 1010 and the second recess 1020, located on the left side of the primary bead 100, jointly define an accommodation groove 107; similarly, the first recess 1010 and the second recess 1020, located on right side of the primary bead 100, jointly define another accommodation groove 107.

The base 103 is surrounded by the first casing 101 and the second casing 102 so as to be positioned in the spherical shell, and the base 103 is leaned against the first casing 101 and the second casing 102. In this embodiment, the base 103 includes a platform structure, and the platform structure is plate-shaped. The base 103 of the primary bead 100 further includes two screw holes 106 respectively located on two opposite sides of the base 103, and the two screw holes 106 are respectively accommodated in the two accommodation grooves 107. The base 103 includes a platform structure in this embodiment, but the present disclosure is not limited thereto. In some other embodiments, the base includes a U-shaped structure. A detailed description of the recessed structure is referred in another embodiment and is disclosed in other paragraphs.

Each of the two spacer beads 200 defines a first side 201 and a second side 202. The two first sides 201 of the two spacer beads 200 are detachably disposed on two opposite sides of the primary bead 100, respectively. Specifically, each spacer bead 200 includes a thread structure 203 located on the first side 201.

The bead string 300 is connected to the second sides 202 of the two spacer beads 200. In this embodiment, the bead string 300 includes multiple subsidiary beads 301 and a stringing member 302. The stringing member 302 is, for example, an elastic rope. The subsidiary beads 301 and the spacer beads 200 are strung on the stringing member 302. The subsidiary beads 301 are located between the two spacer beads 200; that is, the two spacer beads 200 are respectively adjacent to two opposite ends of the stringing member 302, and the subsidiary beads 301 are located on a middle section of the stringing member 302. The stringing member 302 includes two knots 3020 respectively located on two opposite ends of the stringing member 302. Two opposite ends of the stringing member 302 are tied to form the two knots 3020, and the width W1 of the knot 3020 is larger than the width W2 of the stringing member 302. Each spacer bead 200 has a through hole 204, and a first section 2040 of the through hole 204 is connected to a second section 2041 of the through hole 204. The first section 2040 is closer to the subsidiary beads 301 than the second section 2041, and the width W4 of the second section 2041 is larger than the width W3 of the first section 2040; that is, there is a step between the first section 2040 and the second section 2041, and a bearing surface 20410 of the through hole 204 is formed between the first section 2040 and the second section 2041. Since the width W2 of the stringing member 302 is smaller than the width W3 of the first section 2040 and the width W1 of the knot 3020 is between the widths W3 and W4, the two knots 3020 are respectively leaned against the two bearing surfaces 20410 of the two spacer beads 200, such that the stringing member 302 is fastened with the two spacer beads 200. In this embodiment, the stringing member 302 is fastened with the spacer bead 200 by leaning the knot 3020 against the bearing surface 20410, but the present disclosure is not limited thereto.
